Description FRLinux 2009-09-06 16:35:09 UTC 
I have been pointed to your project since my distribution cannot seem to be able to fix it. I filed the original bug there : https://bugs.gentoo.org/show_bug.cgi?id=283833


Back on xorg 1.3 i had that issue where xinerama would not assign the correct
resolution when opening a window or watching a video on second screen (which in
my setup is a 32' Sony TV). The fix was this: 

--- a/randr/rrxinerama.c
+++ b/randr/rrxinerama.c
@@ -428,6 +428,14 @@ RRXineramaExtensionInit(void)
        return;
 #endif

+    /*
+     * Xinerama isn't capable enough to have multiple protocol screens each
+     * with their own output geometry.  So if there's more than one protocol
+     * screen, just don't even try.
+     */
+    if (screenInfo.numScreens > 1)
+       return;
+
     (void) AddExtension(PANORAMIX_PROTOCOL_NAME, 0,0,
                        ProcRRXineramaDispatch,
                        SProcRRXineramaDispatch,

Unfortunately on xorg-server-1.6.3.901-r1, the bug is back and even though the
fix is in the source, the problem is back. I have looked through forums and
bugs but cannot find a solution for this.

I am also using the nvidia-drivers-185.18.31.

Here is the emerge --info stuff, I am using a few masked packages for xorg as i
wanted to help debug the latest xorg on Gentoo.

Please find also attached my Xorg.0.log which might help finding the root of
the problem and my xorg.conf specially crafted for my dual screen setup.


Reproducible: Always

Steps to Reproduce:
1. emerge latest xorg-server
2. connect 2 screens
3. second screen resolution scaling wrong 

Actual Results:  
scaling is sending the video to the right bottom corner of the screen instead
of scaling the full screen, as if virtual resolution was detected to be the
first screen's (1920x1200) instead of second (1360x768)

Expected Results:  
scaling should work on second screen taking into account its own resolution

This bug already happened on an old version of xorg, i found this link which
might help you pin pointing the issue:

X Log of two screens connected with second not selecting the right virtual resolution
Comment 3 FRLinux 2009-09-06 17:50:05 UTC 
I have created an attachment (https://bugs.freedesktop.org/attachment.cgi?id=29285) which is the X log of the 2 screens connected with the second one selecting the wrong virtual resolution.
Comment 4 FRLinux 2009-09-15 18:08:08 UTC 
Also tried with latest ebuild (1.6.3.901-r2) and xinerama is still broken. Please help.

xorg.conf

in that configuration file, setting both virtual resolutions to 1368 fixes the issue but prevents me to use my first screen as 1920x1200.

@Aaron, CCing you since the nvidia driver is involved.

Thanks
Comment 7 Aaron Plattner 2009-09-16 00:48:57 UTC 
FRLinux, please start X with "startx -- -logverbose 6" and then generate and attach an nvidia-bug-report.log.gz file.
Comment 8 FRLinux 2009-09-16 09:05:28 UTC 
Alright, I actually found the root of the issue, and this is quite disturbing. The issue is not X, but KDE 3.5, i did the same tests on XFCE and it scales as expected...

I am nonetheless including the verbose log, just in case this might be of help...
